To all whom it may concern:

Be it known that I, LOUIS E. CART R, a citizen of the United States, residing at St. Joseph, in the .county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Look Mechanisms; and I do hereby declare the following to be a full, clear, and exact description of 'the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to a door locking mechanism embodying a system of bolts adapted to be thrown by ha ndand a lock for securing the bolts when projected into locking position.

The invention has for its object the pro-.

vision of a lock mechanism for securing single, double or a plurality of swinging doors and which is equally well adapted for laterally or vertically sliding doors, the locking mechanism embodying a system of bolts for securing the door at the top, bottom and sides, and which bolts are adapted to be thrown by "hand from either side of the door.

A further purpose of the invention is the p o is on e la l ek e s em ng he belts he Preieeted iht j eehingn e t en, Sa leek being epe hlehy ha d e k y d p evi eel with 'lateh f r 'eeeurihg the a ag ins movemen when eq ire Other ehiee f and ad ant ge ll be ar parent ehtl ngge hemse ves a t net i r of the i vention is nde tood- Whle the d a ing illus rate. n embed .ment of the ehtieh it i o h uhd etee th t i adap g the s me t meet difie'r h f c n it on and requ rements, v r ou ehen ee the term, propo tion a d mine d ta of ehet uet eh may h re orte t w thou departing m the na ure, etth in ent eh- I Bete ring to th accompanying dra ing sh wing thes parts of t e leeihepp e th i ner si e thereo the b lts heme sho by full hue .inrrejee d pes t en'a id' by igure 2 is a ew i el ation of a Pe ti h e the dee che ng thes Part ef h lock applied to the outer side of the door,

Referring to the accompanying drawin 's, the nnmeral 1 designates door to which the jloek mechanism 'is'applied and 2 represents a complemental part {which may consist of a'doo-f, a jainb or'the like to which it maybe required to secure the door 1 when'closed and in position to be locked. Keepers 3 and 4 are secured to the part 2, the keeper 3 being closed at opposite ends and the keepers 4: being ,open atoneend. to admit of a latch engaging the same by a pivotal movement. Similarly 'construotedflatc'hes 5 are pivoted atone end to the upper and lower portions of the door 1, respectively, and their free ends are adapted to engage the keepers 4. Each of the latches 5'has a longitudinal slot v6 in which operates a pin '7 projecting from a bolt 8 which is mounted to slide in kee ers 9Q Twoslidingbolts 8 are provided, the one for the top of the door and the other for the hottom'of the door. 7 A link 10 conmeets th n r e of eeeih f he b l s 8 with an arm of a bell crank 11, the other a of sa ell rank e n on e te by means of a l k 12 th e o '8 e de y mounted upon the door 1 for movement in a I plate 16.

of the bolt 8. The bolt 13 is slidably mounted in a keeper 1 1 and is adapted to engage the keeper 3 and cooperate with a suitable lock whereby to secure the same when projected into locking position. The part 13 constitutes the main bolt and the auxiliary or supplemental bolts 8 are connected thereto by means of the bell crank 11 and links and 12, and upon operating the main bolt 13, the auxiliary bolts 8 are simultaneously actuated to be projected into locking position or withdrawn so as to release the door 1. The latches 5 are simultaneously operated with the bolts by reason of the pin and slot connections thereof with the bolts 8. f A handle 15 is attached to the main bolt 13 and admits of operating the latch mechanism from the inner side of the door. A plate 16 disposed upon the outer side of the door 1 is connected to the main bolt 13 by means of bolts 17 which pass through a slot 18 formed in the door 1. The bolts 17 also serve to connect the handle 15 to the main bolt 13. A handle 19 is attached to the A wear plate 20 is applied to the outer side of the door 1 and has a slot to correspond with the slot 13 through which the bolts 17 pass.

A suitable lock is applied to the door 1 I and cooperates with the main bolt 13 to secure the same when projected into locking position, whereby to prevent unauthorized operation thereof. This lock comprises a casing 21 from which a barrel 22 projects. Pivoted dogs 23 are disposed within the casing 21 upon opposite sides of the main bolt 13 which slides through the casing and is provided in opposite edge portions with notches 2 1 to receive the engaging ends of the dogs 23. A longiudinal slot 25 formed in the main bolt 13 receives a spindle 26 to which is secured a hub 27 having opposite extensions which are connected by means of links 28 to the dogs 23. Contractile helical springs 29 cooperate with the dogs 23 to draw the same inward to cause their projecting ends to enter the notches 2A when the main bolt 13 is in position to bring the notches 24 in register with the engaging ends of the dogs 23. The spindle 26 projects'beyond opposite sides of the casing 21 and one end receives a fingerpiece 30 and its opposite end is enlarged and provided with fingers 31 located in a groove 31 at the inner end of a plug 32 which is slidably mounted in the barrel 22. The enlarged end of the spindle 26 projects into the barrel 22 and an expansible helical spring 33 normally holds the plug 32 pressed outwardly. A key guide 3 1- is rotatably mounted in the outer portion of the barrel 22 and is retained in place by means of pins 35 secured to the barrel and entering an annular groove 36 formed in the outer side of the guide 34, whereby to retain the latter in predetermined position. A key 37 is adapted to be introduced through the guide 34 and engage the plug 32, whereby to rotate said plug and the spindle 26 to move the dogs 23 so as to release the main bolt 13, whereby the lock mechanism may be actuated to release the door 1. Notches 38 are formed in opposite edges of the key 37 and when the key is pressed into the barrel 22, the plug 32 is moved inward against the tension of the spring 33, thereby bringing the notches 38 in position to clear the legs of the pin 35, whereby the key may be turned to throw the dogs 23 and release the bolt 13. An escutcheon plate 39 applied to the outer side of the door 1 receives the outer end of the barrel 22.

A cap plate 10 closes the casing 21 and is provided at its inner side with a sliding latch A1 which is adapted to engage the spindle 26 and prevent rotation thereof. A fingerpiece 42 projects from the latch 11 and provides convenient means for moving the latch so as to engage the spindle or release the same whereby the lock mechanism may be operated. Slots A3 are formed in opposite sides of the spindle 26 and are adapted to receive portions of the latch bordering upon opposite sides of a slot 4 1 formed therein.

\Vhen the main bolt 13 is projected into locking position, the auxiliary bolts 8 and the latches 5 are also projected into locking position, thereby securing the door 1 at five points and'in the event of the part 2 being a swinging door, it is secured to the door 1 by the main bolt 13 and the latches 5 and since the door 1. is secured to the frame at the top and bottom, it follows that both doors 1 and 2 are made secure when in closed position. hen the latch l1 is moved into locking engagement with the spindle 26, the latter cannot be turned either by the key or by means of the fingerpiece 30, hence the lock mechanism is made secure, but when the latch 41 is moved into position so as to release the spindle 26, the lock may be operated either by means of the key 37 or the fingerpiece 30 and when the dogs 23 are dis engaged from the main bolt 13 the same may be moved by hand through the instrumentality of either of the handles 15 or 19, and when the bolt 13 is disengaged from the keeper 3, the bolts 8 clear the door frame and the latches 5 release the keeper 4 so that the door 1 may be swung into open position.
